Up. . . Down. . . Up. . . Down

[Dave5Cs]

These are mine "Airbagit" or on e bay 199.00 Aprox two gauges with 2 needles each and 4 paddle valves for up and down simple comes with the t fittings for hoses on the back. I cut out the leveling valves, don't need them anymore either like John said.

So do we really need the leveling valves on our coaches?  If not why would we want to keep them?

[Dave5Cs]

They kept a smooth ride for the passengers when in service.

Ok, I guess that makes sense. I'm still learning. How's the best way to figure out the right pressure's? Trial and error? And how touchy is it? If your wrong does it put undue stress on the divine? And does that goof up your steering geometry?  Sorry about the questions.  =-O

No Problem
I'm not sure of the ride height of the PD 4107. Look in your manual if you have one or someone that knows can chime in. Measure to the ground with coach loaded and after you have the height set note the pressure on you leveling gages and you are set. If you are off a bit it won't matter much.

    In the manual position, the air leveling valves are disconnected from the leveling system and bags are controlled by the push to inflate or pull to deflate individual corners.  You would have six? (don't remember  exactly without my schematic) 1/4 inch nylon lines going to unit. Air supply, air feed from selector valve and one line to each corner. Some do this with solenoids, some eliminate the leveling system. All can work fine. The supposed twisting of the body is not a concern to me with a GM coach. Maybe can happen on a rust laden Eagle or MCI.

[Dave5Cs]

Not on my MCI 5Cs mostly aluminum and Stainless Steel, not much steel on it. But they are monocoque frames. I had very little if any rust because it was in Saudi desert and then California.

      My "air bags are steel"!!   I'd like to take a couple of leaves out and add "helper bags" to even out the ride and allow leveling.  I'd love to have a schematic on one of these systems if someone would be so kind to post it!   Would that be convenient for someone?   Thanks,  BH

[chessie4905]

   You take out leaves and might introduce swaying. If you proceed, consider adding front and rear stabilizer bars.

Bruce,sometimes today I will find the drawing of the Eagle air bag leveling system used on the torsion it should work with springs

[Jim Eh.]

This is funny I just posted a plumbing schematic for that system on Face Book

  I'd love to have a schematic on one of these systems if someone would be so kind to post it!

Ditto ...

It is a huge image. You may have to scroll left/right to see the whole thing.

THANKS, that helps a lot.  Makes me wish I hadn't just put on new leveling valves on the rear  .  I will keep this for future reference.

    Thanks, Chessie, I'll look at that.  I have a lot of suspension capacity - my bus was built to carry 99 people and the suspension is harder than a red-headed divorce lawyer's heart!   I'm guessing that no matter what I do, I'm going to have a pretty substantial re-spec job as part of it.

    And THANKS from me, too, for the diagram!
